SHUTTLE-OPERATING MECHANISM FOR POWER-LOOMS.

SPECIFICATION formingpart of Letters Patent No. 593,941, dated November16, 1897.

Application filed July 23, 1896. Serial No. 600,261. (No model.)Patented in Germany June 9,1895, No. 85,292.

panying drawings, wherein- Figure 1 is a front elevation, and Fig. 2 aside View, of a loom with myimproved mechanism, showing its positionwhen the batten is started from its lowest position and theshuttle-operating mechanism on the righthand side of the loom unloaded.Fig. 3 is an elevation, Fig. 4 a side view, and Fig. 5 a detailed topview,of a part of a loom,showing my improved shuttle-operatin gmechanism in action when the batten is moved upward. Fig.

6 is an enlarged detail, a side view of the shuttle-operatin g mechanismset in position, attained when-the batten reaches its highest position.Fig. 7 is a sectional view on line 7 7 in Fig. 6. Fig. 8 is asimilarview as Fig. 6, showing the shuttle-operating mechanism afterdischarging the shuttle. Fig. 9 is a-section on line 9 9 in Fig. 8.

Similar letters of reference indicate corresponding parts in all theviews of the drawings.

My invention relates to power-lo0ms; and it consists of thehereinafter-described mechanismfor operating the shuttle, comprisingdevices for setting springs actuating the shuttle on both sides of theloom simultaneously when the batten moves upward and releasing themalternately when it returns.

The mechanism is particularly applicable to power-looms havingperpendicularly-moving batten, the striking-bolts, pressed against bythe springs, being driven outward against the pressure of the springswhile the batten is moved upward, then arrested by ratchetbars,holdingthe springs set,and then released alternately by mechanism operatedindependently of the batten from the driven shaft. The shuttle moves onthe reed and the driving mechanism is attached to the batten.

The frame of the loom shown in- Fig. 1 is composed of the two standardsa and their connecting-ties. The batten bis shown in its lowestposition.

A is the main driving-shaft, and d disks set thereon and driving,through crank-pins d and connectingrods d, batten b on slideways 0.

Springs k are flat and made of tempered steel. Their lower ends arescrewed to brackets Z Z, secured to the batten b and projecting downwardat a right angle to it.

Bolts 76 slide in sleeves is, secured to the batten. They are made,preferably, round and provided with a spline s19. Sleeves 7e areprovided with a corresponding groove,wherein spline s19 engages to keepthe bolts 10 from turning. The heads of the boltskare forked and rollers10 are set on pins 2, pillowed thereinto relieve friction between thebolts and the springs Upon the same pins z are set rollers z, runningupon rails h of the setting-brackets.

Brackets h, forming sloping rails h, are attached on the outside of thestandards a, of the frame, as shown in Fig. 5 in detail. Rollers 'iengage against the sloping rails h when the batten bis moved upward, andas the batten 11 moves upward bolts 7c are drawn outwardly untilratchet-bars n slide into corresponding recesses 'rc, (shown in Fig. 7,)provided in the bolts It, arresting them in their extended position.This part of the mech anism is illustrated in detail in Figs. 6, 7, 8,and 9. Ratchet-barsn are pivoted on bolts 71 set in bars 5, and springsn attached to their outer ends, draw themdownward. The other ends of theratchet-bars n, projecting beyond the bolts 11, are connected by links rand r to brackets r screwed to the bottom of the shuttle-way.

The releasing of the bolts k for the purpose of imparting motion to theshuttle is accomplished by mechanism operated from the driving-shaft andlifting alternately the ratchetbars on each side of the loom. Thismechanism is arranged as follows: I

To the shaft 15, driven from the main driving-shaft A by cog-wheels gand g, is keyed cam 0 having two diametrically opposite sections 0 'and0. Booking rod 0, pivoted. to bracket 0 engages with its forked lowerend 0" the cam 0 and imparts the rocking motion produced thereby to thehorizontal bar 0. On

each end of the bar is a block 0, and as the bar 0 is moved to and frothese blocks strike alternately against the ratchet-bars 01, while thebatten moves downward, thereby lifting them and releasing thebolts,which, driven by the rebounding action of the springs, impart aforcible motion to the shuttle.

I claim as myinvention and desire to secure by Letters Patent- Inmechanism for imparting motion to the shuttle of a power-loom, thecombination of a batten, sleeves, having keywa-ys, secured to the endsof the shuttle-way; striking-bolts, having forked heads, sliding in thesleeves; splines set in the bolts; pins or spindles set crosswise in theforked heads of the strikingbolts and projecting to one side therefrom,antifriction-rollers set 011 these pins or spindles between the tines ofthe forked heads; downward-extending brackets secured to the batten, oneon each end; springs, secured to the ends of the brackets and engagingthese rollers; antifrietion-rollers set on the projecting ends of thepins or spindles; sloping rails,

secured to the standards of the loom-frame in position to engage theseouter rollers, ratchetbars, pivoted to the ends of, the shuttle-way andadapted to drop into recesses provided in the striking-bolts; springsdrawing the ratchet-bars downward; a shaft pillowed in the standards ofthe loom-frame above the driving-shaft a gearing transmitting the motionfrom the driving-shaft to this shaft; a spiral cam, set on this shaft; ahorizontallydisposed sliding bar, vertically upward proj ectin g blocks,set one on each end of the horizontally-disposed sliding bar; a rockingrod, engaging with its forked end the spiral cam, and shifting thesliding bar to and fro, thereby alternately lifting the ratchet-bars andreleasing the striking-bolts.

In testimony whereof I have signed thisspecification in the presence oftwo subscribing witnesses.
